BETA energy storage systems feature multiple redundant protections against unlikely thermal runaway events, communications glitches, non-uniform discharges and environmental interruptions. The packs we deliver to our partners meet stringent requirements per DO-160G and minimize additional hazards during a worst-case thermal runaway condition. BETA energy storage systems deliver safe energy across multiple aircraft platforms.
Batteries are among the most safe and stable potential energy packages that humanity has ever captured.
How can electrical energy and power be compared to gallons of fuel?
If you typically have 450 gallons of usable fuel and burn 150 gallons per hour, you can fly for 3 hours. With electricity — if you have 450 kilowatt-hours of usable energy and are using 150 kilowatts, you can fly for 3 hours.
The energy storage system that powers the aircraft is composed of multiple battery packs connected together in parallel through a distribution system designed to provide safety and redundancy for all power requirements.
BETA battery packs are built from thousands of individual battery cells. These work together to achieve market-leading energy density with maximal redundancy.
These features ensure occupant safety, and also provide first responders safe, easy access in the event of an emergency.

BETA’s battery facility allows our team to test above and beyond regulatory safety requirements. We put our families in our aircraft, and we ensure pack safety to the highest standards.
Our rigorous safety standards and company culture has guided our path toward a holistic approach to ensuring all of our battery packs meet the highest regulatory and industry standards. The BETA facility in St. Albans, Vermont provides ample space to test and iterate the design of our products.
BETA packs are on the path to certification and have endured years of test and validation against the industry's toughest regulatory standards. Our 40,000-square-foot test facility gives BETA in-house, state-of-the-art test capability for nearly all certification credit testing and the tools that will allow us to verify future aircraft designs that vary in size and power.
BETA's production facility is equipped to provide our customers with advanced battery technology as it reaches the market, and secure, long-term business planning solutions with our buy-back program.
Designed, tested and produced by an expert team of electron whisperers, BETA battery packs power vehicles across all platforms and electric propulsion types, meeting every customer's needs at the point of operations.
